存在相同PackageName

Error message

存在相同PackageName

What it means

After passing name validation, Create queries sys_auto_code_package for a row with the same packageName AND template. If such a record is found (query does not return gorm.ErrRecordNotFound), creation is refused to keep package names unique per template.

Solutions

1. Query existing packages first (GET autoCode/package list) and reuse or delete the existing one before re-creating.
2. Pick a unique packageName, or intentionally reuse the existing package when generating new code.
3. If the leftover record is stale, delete the old package entry via the auto-code UI/API, then re-create.

Example fix

// before: blind create
POST /autoCode/createPackage {"template":"package","packageName":"crm"}
// after: check then create or reuse
const pkgs = await api.getPackageList()
if (!pkgs.some(p => p.packageName === 'crm' && p.template === 'package')) {
  await api.createPackage({ template: 'package', packageName: 'crm' })
}

const exists = (await api.getPackageList()).list?.some(
  p => p.packageName === name && p.template === template
)
if (exists) {
  throw new Error('存在相同PackageName，请先删除或复用')
}

try {
  await api.createPackage(payload)
} catch (e) {
  if (e?.msg === '存在相同PackageName') {
    const use = await confirm('包已存在，复用该包继续生成？')
    if (use) targetPackageId = await findPackageId(name)
  } else { throw e }
}

When it happens

Trigger: POSTing a new package whose (packageName, template) pair already exists in sys_auto_code_package; retrying a creation that already succeeded; same name but different template passes (the uniqueness is per-template).

Common situations: Double-clicking the submit button; re-running an automation script; re-creating a package after deleting its generated code but not its package record.
